Mannosylglycerate synthase () is an enzyme with systematic name GDP-mannose:D-glycerate 2-alpha-D-mannosyltransferase. It catalyses the following chemical reaction
The enzyme characterised from transfers a mannose sugar unit from GDP-mannose to D-glyceric acid, giving 2-(α-D-mannosyl)-D-glyceric acid, with guanosine diphosphate (GDP) as a byproduct. In thermophilic bacteria, the product protects against osmotic shock and in some cases is produced in a two-step process that uses mannosyl-3-phosphoglycerate synthase to give a phosphoglycerate intermediate which is hydrolysed by the enzyme mannosyl-3-phosphoglycerate phosphatase.
